Refined Aluminum Grain Refiner Ingots from Mexico
Refined aluminum grain refiner ingots at 99.7% purity contain trace amounts of titanium and boron for grain refinement during casting. Despite these additions, the ingots remain non-alloyed as the other elements stay within Chapter 76 limits. They are classified as unwrought aluminum under tariff item 7601.10.00.
